IMPROVEMENT IN HEATING-STCVS.

The Schedule referred to in these Letters Patent and making part of the same To all persons to whom these presents may come Be it known that I, MIGAJAH Gimnmn BURLEIGH, of Soniersworth, of the county of Straiord and State of New Hampshire, have made a new and useful ini'ention having reference to Stoves or Furnaces; and

do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, ,of which- Figure 1 is a front view;

Figure 2, a longitudinal section;

Figure 3, a transverse section; and

Figure 4, a top view of the fuel and ash-chambers. of a stove, with parts immediately adjacent thereto, the same exhibiting the main features of my invention.

In such diawiiigs- Y A denotes the fuel-chair'iber or pit, which is circular in forni, and inclosed within an elliptical case B,

Passages C C, for discharge of smoke from the fuelchamber, lead tlii'ough the bottoma of the case B into a separate chamber, D, arranged within the lhase E of the stove.

Theiash-chaiiiber or pit is formed'by a box, F, which projects downward from the bottom a into the chamber D, the said box F being so disposed that there shall be a clear or open space, c, between its bottom d and thatof the chamber D;'also, so that there may be a smoke-space, e, around the ends and back of the said box F. The said smoke-spaces c and e freely openinto each other.

From the above it will be seen that the ash-cham- I bei orpitvissuspended within the smoke-space ofthe able access to be had to the interior 'of the hase oi' the iioor thereof whenever it may be desirable to remove therefrom any ashes or deposits made thereon. The grate shown at His circular in form, and is ai'- ranged within a corresponding opening, I, made through vthe bottom of the fuel-chamber and into thefash-chaniber. This grate, at its center, is pivoted to and snpported in a horizont-al bar, K, which, at its opposite ends, has journals h h, to rest in suitable bearings yi i', projecting from the bottom of the fuel-chamber.

The grate also rests onjcwo ears, It' k', extended from the sides Iof its opening I. Furthermore, there is a notch or opening, l, made iii the grate from its circumference. f

Figure 5 exhibits a top iiew of and Figure 6 a transverse section of thegrate, such sect-ions being taken through a socketed arm, mi, which is extended from the grate in maniier as rep i'eseii.ted, the socket of the arm being shown at n.. V

Through the front of the stove is a horizontal slot,

0, provided with a standard or projection,p, arranged within it, in manner as seen in fig. l.

` By inserting a harwithin the slot o, and extending sncli bar into the socket of the arm mf, a person, by means of such bar, may oscillate the grat-e horizontally in its central position,.tlie projection p and one end of the slot serving as stops to determine the extremes 4of such oscillations. By raising the bar over the projection pand into the space between it and the next adjacent end of the slot c, the notch lof the grate will be brought directly over the neigt adjacent supporting ear It. When the grat-e is in this situation it may be dumped or revolved with its supporting shaft, in order to discharge any coals in it into the ash-drawer L arranged within the ash-chamber, so as to be capable of being slid into or removed therefrom upon ways or supports X X, as occasion may require.

To each of thel two opposite sides of the ash-chamber, and directly over the said ash-,drawer or its sup- 'pots, there is-applied an inclined chute or deiector,

M, whose purpose is to prevent ashes, while dropping from the grate, from lodging on lthe upper edges of thev ash drawer, and to effect the dischargeof such ashes into such drawer.

' rlhe mouth of the ash-pit, aswell as .that of the; 'throat N of the fire-place, I lprovide with afl-ange, q,

to extend from and around it and to close into-and it closely to the sides of a chamber or space, fr, made inthe door 0 or P of sneli asli-pit or throat.A Instead.v of the above, the edges of the chamber of the door may close into a groove or rebate in the irame'ot' such door, the object being to render the joint of the door l,

when closed tighter to the passage of air than it otherwise would be. Y

There is at the rear of thechaniber D an o pening. lr', communicating with a chamber, s, constituting part 'of the escape-flue of the stove, the funnel being, when the stove is in use, projected upward, and so as to open out of such chamber s.

To this opening there isa damper, t, which is connected with the opening by one or more hooks u, each of which is extended from-,the damper-'and through a hole or .slot in the casing,- constituting the backof the chamber D. The said hook serves as a hinge, so as to enable the damper to be opened or closed.

In the damper there is a slot, u', in which is fitted aistem, e, of the peculiar shape asrepresented. This damper may he readily inserted in place through the opening at the top-of the smoke-box or chambers. lhe stein goes through a slot, w, mad'e in the back of the chambers.

i tions or positions.

The damperfstem is provided with an ear or projection, x, which is arranged at an obtuse angle with the stem, and serves as a stop to arrest the damper when drawn fully open. At the vertex of the said angle there is-a curved notch, 1 ,to enable the stem to straddle upon and engage with the damper.

The stern on its lower edge is provided with a series of notches, z, to catch upon the bottom of the slot wg'in order to set the damper to different inclina- This construction of4 the damperstem enables it to be easily applied to the stove and damper, or to he removed therefrom, as occasion may require.

In astove lnade'as described, the' combustion of the fucl may bcpregulated, andthe heat thereof bo ntilized to excellent advantage.

T he suspended ashpit or box arranged with the chamber D, as set forth, enables the smoke to pass entirely underneath the ash-pit, so as to heat the en tire bottom of the chamber D, whereby heat therefrom may be radiated outwardly' into the surrounding atmosphere,` and thus be employed in heating the same.

I claim, as ot' my inventien in the heating apparatus, as described, the following, viz:

Y The arrangement of the ash-pit F in the -chamber D,viz., so as to be suspendedfroui or extended down from the top thereof, and have a clear space for .the smoke to course through, between the ,bottom of the ash-pit and that of the chamber D, before escaping through the opening at the back of such chamber, as explained.

Also, the damper t, as provided with the hookV or hooks u, as and for the purpose set forth.

Also, the slot o, as provided with the stop p, in combination with the grate, supported by means and having the notch l, as set forth.

Also, the grate, as made with the notch l, as and for use as explained.

Also, the arrangement of thcdeeotors M with the ash-pit D, and the ash-drawer L, and its supports X X.

Also, the damper-stem lu, asmade with the ear x and the notch 1, arranged with respect to the remain der of the stem, as set forth.
